[SRU][Resolute][Questing][Noble][PATCH 0/1] UBUNTU: SAUCE: ACPI: respect items already in honor_dep before skipping

BugLink: https://bugs.launchpad.net/bugs/2145171

SRU Justification:

[Impact]

Upstream v6.18-rc1 commit 4405a214df146775338a1e6232701a29024b82e1
"ACPI: scan: Add Intel CVS ACPI HIDs to acpi_ignore_dep_ids[]" (also
backported to v6.17.8, v6.12.58), which in effect reverts a not yet
upstreamed Intel MIPI camera patch titled "ACPI: scan: Update HID for
new platform" meant for bug 2090932, and therefore they share the same
symptom:

  [ 4.484426] ov02c10 i2c-OVTI02C1:00: chip id mismatch: 560243!=0
  [ 4.484432] ov02c10 i2c-OVTI02C1:00: failed to find sensor: -6

[Fix]

While this should really be fixed by upstream Intel's CVS driver and
remove the two platforms from acpi_ignore_dep_ids, a sauced change is
made to preserve the honor effect and yet don't introduce potential
conflict with the upstream before any further progress is made.

[Test Plan]

1. Install the kernel from -proposed pocket and reboot into it.

2. Check dmesg has no aforementioned error,

3. Make sure the device appears in the gstreamer device enumeration:

   $ gst-inspect-1.0 icamerasrc
   .....
      device-name     : The input devices name queried from HAL
                        flags: readable, writable
                        Enum "GstCamerasrcDeviceName" Default: 0, "ov02c10-uf"
                           (0): ov02c10-uf       - ov02c10 as sensor.

[Where problems could occur]

No. This restores the hardware enablement effort for the affected
platforms only. For Ubuntu, CVS driver is always available along with
the kernel, and therefore for a device declared _DEP to the two ACPI
devices, the driver can be installed either through ubuntu-drivers or
through oem meta packages.

[Other Info]

While this has been backported to v6.17.8, it affects R and Q. And while
this has also been backported to v6.12.58, and linux-6.8/noble is
tracking stable 6.8 fixes, Noble will be affected soon or later.
Nominate for N, Q and R accordingly.
